There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Where is the temperature sensor?
- Thread starter Warfels
- Start date
It's the ambient air temp, but under the tupperware! Because of where it's placed, it "collects" quite a bit of the engine heat and takes a while to cool back down to real "ambient temp" once you stop - if it ever does! I added the quotes there as it's not really outside, as in the open, so no matter what you do, it's going to be a little warmer than the actual outside temp. It's under the tupperware on the right side, near the frunk. To check/remove it, you'll need to remove the (3) main pieces of tupperware. If you start the bike whilst it's unplugged, it'll set off a couple of codes.
Once you see it, you'll understand why it doesn't sense the actual outside temp. I generally subtract 4-6° to come up with the actual outside temp.

Actually, it IS doing its job - it's just that 'its job' was NOT originally intended to be to show YOU, the rider, the ambient/outside air temp, but rather to provide an 'under the tupperware' &/or 'air intake temp' to the various systems that need to use that info in order to help the engine run at its best - it's probably just that some (sales type, or possibly marketing?? :dontknow: ) tosser thought they could convince the un-aware punters out there (ie, potential but gullible buyers :rlleyes: ) that these Spyders have an 'ambient temp indicator' on the dash & so improve their chances of making a sale, even tho the engineering types told them that that sensor & the info it provided was never meant for that and would almost always be somewhat higher than outside ambient.... :gaah:
So it's only WRONG if you think of it as an ambient air temp indicator, but it's RIGHT & even very helpful for the systems that use the 'under the tupperware/intake air temp' in order to help the engine control systems get things running properly!

I don't remember exactly what I did with mine, but I think I enlarged the hole in the duct it was mounted above. Whether it affected engine performance I don't know, but sometimes I wonder if it reduced my mpg. Other than that it had no effect. The main thing to keep in mind about it is that it is a combination temperature and ambient pressure sensor. I think the main reason it's mounted where it is is to prevent air from ramming against it and causing a higher than actual pressure reading. I put some foam or did something else to keep air from blowing directly on the sensor so that it would do a better job of sensing actual ambient air pressure. But, I do have temp readings that are very close to real air temps! :2thumbs:
As far as reading high I think that is caused more by sunshine warming up the area above the duct. The sensor is in front of the radiator and above the duct so I really don't think it picks up engine heat. One time it registered about 120°F after sitting in the sun for a couple of hours and put the bike into Limp Mode, I think it was. A few hundred feet of travel cooled it down enough to cancel the Limp Mode.

Mine works perfectly... when I go out to the garage in the morning, I know exactly how warm it is in there :roflblack: ... then I start the Spyder. :dontknow:

Between the heat these spyders produce and the sun, you're gonna have a hard time finding a spot to mount the sensor for an accurate air temp reading. On my 2018 I mounted a tiny sensor under one of my mirrors, out of the sunshine, but not quite beyond the reach of the spyders heat. Sitting at a red light you could watch the temp rise degree by degree. It did work fine on the highway when the heat was not rising off the spyder.
This thread has been interesting. I just picked-up a 2021 RT L and noticed the same thing. On the dash screen there is a temperature reading that suggests it is the outside temperature (e.g. 79F). However, if the other posts that suggest this reading is more to do with engine operation, BRP did not think through the posting on the screen. Mine has fluctuated between 66 - 96 over the timeframe of my rides today. The outside temperature has been 64 F max. I found nothing in the manual related to this. I will review again.

Brp has had this setup since day one of production of the Spyders. As an earlier poster mentioned just subtract 4-5 degrees while moving and you will be in the ball park of actual temp. It is the way it is. Bruce

Speaking of air intake temp...
I like cold air/ram air concepts. The Spyders air intake is on the left side above the radiator, right?? But is sure looks restricted at its intake. But it's in a good spot and if it could be opened up somehow - Thoughts???

I just happened to glance down at the temperature display today and in traffic on a 100° day. The display said 156° holy cow! As soon as I went through the light and was rolling again it went back down to about 115° and then, as soon as I got out of town, it went back down to around 100° like the actual ambient temperature. Anybody else seen 156°?

I am a new owner of a 2016 F3 S and am loving the ride. I am trying to understand the quirks real or otherwise. The temperature shows 79° F on starting. Is this a normal experience or is it possible there is a sensor issue? As it is, from a cold start, I cannot believe this is correct. Coolant is full, Oil is correct. I haven't checked the radiator yet, still working on the concept of dissembling and reassembling. Any ideas on the way forward I would be most grateful. :banghead:

Hi Lesue, Congrats on your first post on the Forum proper (didja see that I replied to your post in the Welcome sub-forum? :dontknow: ) and Welcome to the Wonderful Worlds of Spyders, SpyderLovers, and Spyder Ryding and to the Miles of Smiles (and days of pure enjoyment &/or utter frustration! 
) that they all bring!! hyea: :welcome:
I've merged your thread as a post into one of the many existing threads on this subject, cos it really wasn't asking anything new or likely to get a markedly different response; and adding yet another thread asking exactly the same thing yet again only makes it harder for everyone to find the info they need! And yes, I know this is a slightly older thread, but the answer about this hasn't changed since about 2008!!
So please, bear in mind that it ALWAYS pays to Search First, BEFORE starting a new thread; and do some reading up on what's already here! That's one of the great things about this Forum, and most like it - the info & shared experiences will always be here, usually fairly readily retrievable, even if there's lots of threads &/or posts about it. So Search first; do some reading up on what's here; and at the very least, you'll learn something, maybe enough to completely answer your question or possibly only enough to refine your question a bit!
And don't be scared of adding to an older thread - a little bit of thread archeology doesn't hurt, especially if you're expanding the knowledge base or adding to the experiences shared; but it also ALWAYS pays to check the date of the Opening Post in any thread AND the dates on the last few posts in it too, and if you do want to ask a question, maybe don't expect replies from people who last posted in that thread saaayyy, anything from about 5 to 14 years ago, especially if their usernames are Red or Grey, cos that means they aren't really around on the boards these days. :lecturef_smilie:
All that said, as you can see from reading thru the rest of this thread, your temperature gauge is pretty much doing the same thing as everyone else's; that sort of higher temp is normal; there's nothing wrong with it; you don't need to worry about it &/or even try to 'fix' it, cos that might have unintended consequences; and you'll get used to it pretty quickly as one of the quirks BRP has given us just to keep us on our toes! And there's more of them too - just don't rely on your fuel gauge &/or low fuel warning light always being accurate either! Just use one of your trip meters to track how far you go between filling your gas tank & work out how far you can safely go without ever running the tank dry & maybe damaging things. :thumbup:
Did you check out the Spyder Muster Website that I mentioned in your Welcome thread? Any chance you might be able to catch up with them at Bathurst over the coming weekend? :dontknow:

I haven't seen 156°F Rockdog, but then my Spyder's temp display is set to show °C - do you think it counts that I've seen over 70°C displayed?? Or that I've had the engine shut down &/or refuse to start cos the ambient temp under the tupperware was too high even tho the true 'ambient temperature' wasn't?? :dontknow:
I must admit that the first time it refused to start due to an over-temp warning it nearly gave me a bleedin' heart attack!! :yikes: I'd left it sitting in the sun for about 5 mins on an unshaded servo fore-court after topping up with gas on a warm day - but it wasn't really a 'hot day' by any means!! :banghead: It didn't take me long to work out it was cos the sensor was reading the temp under the tupperware (that had the sun shining on it) & on top of the engine, pretty much exactly in the maximum heat soak area AND where all the heat reflected off the concrete ended up, so that simply rolling the Spyder into the shade & letting it sit & cool for about 5 mins sorted it; then as you found, once I started riding again it rapidly came down to about 50°C without any concerns or further issues! :thumbup:
